SPINDLE-BEARING.

To all lwhom t may concern Be it known that I, THOMAS J. FEGLEY, acitizen of the United States, residing in Philadelphia, Pennsylvania,have invented certain Improvements in Spindle-Bearings, of which thefollowing is a specification.

The object of my invention is to make a spindle bearing especiallyadapted to a breast drill and which can be positively held in positionand can be readily removed when desired.

In the accompanying drawing Figure 1, is a side view of a breast drill,partly in section, illustrating my invention; Fig. 2, is a side view ofa breast drill; Fig. 3, is an enlarged view of part of F l in section;Fig. 4, is a perspective view of the parts detached; and Fig. 5, is aview et a modification.

A is the frame of a ratchet breast drill, having bearings a, and a3 forthe spindle C, and projecting from the frame is a stud 5 on which is agear wheel B provided with a handle b by which it is turned.

E is the carrier for the pawls e, e of the ratchet mechanism, and e is akey extending through the carrier and into a longitudinal slot'c in thespindle C, so that the spindle will turn with the carrier.

On the spindle C are ratchet wheels l), D', one at each end oit' thecarrier and with which the pawls engage. On each ratchet wheel arebeveled pinions, respectively, which mesh with the wheel B. The positionof the pawls is controlled by a shifter e2.

In order to hold the spindle C .firmly in position and yet allow it torevolve :freely in its bearings, I groove the spindle at c" near itsinner end, as shown in Fig. 4, and apply a slotted collar I to thespindle; the slot z' being of such size as to allow the collar to enterthe groove, as shown in Fig. 3. The collar rests on a shoulder r2 in arecess in the extension a of the bearing a and a hardened screw plug Gis screwed into the recess so as to bear against the end of the spindle,thus the spindle is held longitudinally betweeny the shoulder a2 and theplug G. On the opposite end of the spindle is a chuck N and in Fig. 1the stem n ot the chuck is threaded to receive the threaded'Specification of Letters Patent.

end of the spindle, and when the chuck is close to the bearing a3, as inFig. l, the spindle cannot be removed even if the plug G is detached,but after the chuck N is unscrewed then the spindle can be movedlongitudinally until the collar I is beyond the end ot the extension a',when it can be removed and the spindle withdrawn in the oppositedirection. In some instances the chuck N may be located some distancefrom the bearing a3, as in Fig. 5, when this construction is used thespindle can be moved longitudinally as soon as the plug Gr is removed.

F is a detachable handle having a loose screw threaded sleeve f, held tothe socket end of the handle by a spring ring f adapted to a groove inthe handle and resting under the internal flange of the sleeve. Theextension a fits snugly in the socket end of the handle F and the sleeveis screwed onto the threaded portion of the extension as Thisconstruction is illustrated and claimed in an application for patentfiled by myself and George O. Leopold on March 2nd, 1909, under SerialNumber 480,980.

I claim The combination of a frame having bearings, a spindle mounted inthe bearings and having a longitudinal slot and an annular groove nearone end, means for turning the spindle, having a key extending into theslot in the spindle, one bearing having a recess, a collar mounted inthe recess and eX- tending into the groove of the spindle preventing thespindle moving in one direction, a plug secured to the bearing andresting against the end of the spindle, the key and slot connectionallowing the spindle to move longitudinally in the bearings to projectthe collar so that it can be removed from the spindle, after which thespindle can be withdrawn.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
